MAGNETIC WENDOW SHADE.

SPECIFICATION forming part of Letters Patent No. 302,616, dated July 29, 1884.

Application filed May f0 ctZZ whom it may concern.-

Be it known that I, HENRY D. WINTON, a citizen of the United States, residing in the town of VVellesley Hills, in the county of Nor folk and State of Massachusetts, have invented a new and useful Improvement in VVindow- Shades, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to provide a simple and durable means of holding and adjusting a window-shade at any desired point by means of permanent magnetism. Iacoomplish this object by means of the apparatus described in the accompanying drawings, in which- Figure l is a front view of a railroad-car window with a spring-roller shade of the pattern in general use. Fig. 2 is a section through the window on the line a .r, Fig. 1.

Similar letters refer to similar parts th rough out. My preferred method of constructing my invention is as follows: In the lower end of the window-shade A, I insert a longitudinal bar, B G, which is made of steel and magnetized, so as to form a good permanent barinagnet. It is secured in the leather flap of the shade by sewing it between the leather. The ends or poles of the bar-magnet are allowed to project a short distance on either side of the shade, as shown at a a, Fig. 1. Secured to the sides of the window-flame are two softiron bars, D E, F G, which are finished to present a smooth surface. The shade Abeing hung on a spring-rollenit can be raised or lowered to any desired point. WVhen it has been adjusted to the right height to suit the operator, it can be pressed against the iron bars I) E, F G, and the poles of the bar-magnot coming in contact with the soft-iron bars 13, 1884. (No model.)

causes the shade to be held in the position in which it has been placed by the magnetism in the bar-B G. A bar of the same material as the bars D E, F G is connected to the upper part of the frame, and in contact with the bars at each end, as shown at H, Fig. 1. In this manner a keeper will be formed for the permanent bar-magnet when it is in contact with the bars D E, F G, so that it will not lose any of its magnetism.

\Vhen catches are secured to the windowsash, as shown at I, Fig. 1, notches may be made in the side of theiron bar F G, as shown at b b, to serve as catches to secure the window when it is open or closed.

I do not confine myself to the exact construction here described, however, as other means of accomplishing the same ends may be used-as, for instance, placing horseshoe-magnets in the ends of the shade and securing the iron bars to the window-sash.

I am aware of the use, prior to my invention, of catches, stops, and holds for the purpose of securing window-shades at desired points. I therefore do not claim the means of accomplishing this object, broadly; but

Vhat I do claim as new, and desire to se cure by Letters Patent, is

The combination, in a window-shade, of a permanent magnet and the window frame or sash provided with soft-iron bars, in the inanner and for the purpose herein described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 6th day of May,

HENRY D. W INTON.
